The “isoinfo” command is a command-line utility that is used to extract information from ISO 9660 (International Organization for Standardization) disk images. ISO 9660 is a standard file system format for CDs, DVDs, and other optical media. The “isoinfo” command can be used to display information about the structure of an ISO image, extract files from an ISO image, and verify the integrity of an ISO image.
It’s also important to note that while ISO 9660 is a standard format, not all ISO images follow the same standard, “isoinfo” may not work correctly with all ISO images, particularly if they are not compliant to ISO 9660 standard.
If you encounter the below error while running the command isoinfo:
